摘要/Abstract

摘要： 　利用Xpa th 表达式所具有的特点, 实现了对XM L 文档授权与安全访问控制方案。该方案不直接搜索XM L 文档和DOM 树, 而是由XM L 及AC L 创建一棵XAC T(XML 访问控制树)。XAC T 上每个节点包含了用户的访问控制权限, 搜索中使用的路径表达式(XPE)可直接寻找到每一个XACT 节点。所以, 使访问控制粒度可达到每一个XM L 语义元素。

关键词: XM L, 　路径表达式, 　访问控制模型

Abstract:

　Making use of the characteristic of Xpath expression , the document license and the safe accessing controlled scheme of the XML document was put forward.Instead of directly searching XM L document and DOM tree , the scheme sets up a XAC T which is created through XML and ACL .Each node on the XACT contains the accessing controlling limit of a use r .To search the XM L path expression (XPE)can find directly each node on the XAC T.So , the accessing controlling granularity can reach each XM L semantic element.

Key words: XML, , Path expression, , Access control model
